dota2cat

This is an updated version of the dotacat crate. The original crate's name was a pun on lolcat (because DOTA is a similar game to LOL), so I named mine "DOTA 2 cat" :L

The only real difference between this crate and the original is that I've updated the dependencies, modernised it to use Rust edition 2021, and fixed an issue with a breaking change in clap.

Installation

dota2cat can be installed with cargo, Rust's package/dependency manager:

cargo install dota2cat

To more easily facilitate replacing dotacat with dota2cat, the executable is still named dotacat.

The original README continues below.

dotacat

dotacat is meant to be a replacement to lolcat. If you're not aware, lolcat is a rather silly program which behaves like cat, but produces a colourful, rainbow output.

Why?

Speed!

$ time echo hi | lolcat
real    0m0.422s
user    0m0.393s
sys     0m0.028s

I use lolcat in my .bashrc file, so this amount of time is not ideal for me.

In contrast:

time echo hi | dotacat

real    0m0.045s
user    0m0.030s
sys     0m0.020s

Why the name?

Because Dota is better than LoL (According to people - I play neither)

Installation

If you have cargo installed, just run: cargo install dotacat

If not, head over to the releases page and download the latest release. Then run:

chmod +x dotacat
sudo mv dotacat /usr/local/bin
